Outstanding Performance in Underwater Technology

Tritech Positioning & RAMS™USBL, MRU, INS & Integrity Monitoring

Motion & NavigationUSBL, MRU & INS

• USBL: • Tritech MicronNav USBL – the MicronNav system is an

innovative USBL tracking system designed for small ROV / AUV

• MRU: • iGC – (Intelligent Gyro Compass) heading sensor and

motion reference unit (MRU) for numerous ROV and AUV applications

• iFG – (Intelligent Fibre-Optic Gyro) provides additional heading stability when combined with the Tritech iGC

• INS:• Andante Micron Inertial Navigation System (INS) – has

been developed to allow small subsea vehicles the ability to obtain previously unattainable position stability and has been designed to work seamlessly with Tritech’s MicronNav USBL system

Internal NavigationTritech Andante Micron INS


Internal NavigationAndante Micron INS

• The Basics:• MEMS

• ‘Micro-Electro-Mechanical Systems’ are components that are micro in size and provide a range of movement measurements; providing acceleration and rotational inertial measurements

• Magnetic or FOG or RLG• The accuracy of the INS system improves with the quality

of the heading sensor• Magnetic sensors are not suitable for use where operations

are within a steel environment for extended periods

• North Seeking or Not-North Seeking?• Survey requirements will require North Seeking however a

relative solution may be more than adequate



• ANDANTE:• Tritech Friendly Installation

• Integrates seamlessly over one Tritech communication channel• Seamless integration with Tritech MicronNav and other Tritech sensors



• ANDANTE:• Enhanced Position Stability

• Spikes in USBL data are taken out automatically allowing for use in extreme environments



• ANDANTE:• Mission Planning

• GUI supplied with system allows waypoint entry and tracking of ROV



• Andante:• ROV Control

• System can be configured for automatic control of ROV



• Andante:• ROV Control



• Beyond Andante:• Proven capability

• Over 200 integrated systems already in use• Micro ROV, WROV & AUV• 6000m systems and FOG based IMU


Motion Reference Unit (MRU)Tritech iGC and iFG


Tritech iGC and iFGMRU

• iGC:• Proven capability

• The Intelligent Gyro Compass (iGC) provides essential movement data not available from widely used magnetically slaved gyro and flux gate compasses

• iFG:• Additional heading stability

• An on-board processor manages the gyro sensor interface, mode selection, power supplies and water ingress sensing (for use if the iFG is mounted inside its own pod).
